摘要

Foliar application of nutrients, namely, Ca(NO_2)_2 (0.5 and 1.0%), CaCl_2 (0.5 and 1.0%), K_2SO_4 (0.5 and 1.0%), ZnSO-4 (0.5,1.0,1.5 and 2.0%) and CuSO_4 (0.5,1.0,1.5 and 2.0%) in improving fruit quality of litchi cv Bombai was assessed during 1996 and 1997. Among nutrients, application of 1.0% ZnSO_4 as foliar spray significantly increased total soluble solids, total sugar, reducing sugar and pH content of fruit juice with a considerable reduction in acidity. Apart from ZnSO_4 (1.0%), CuSO_4, at 1.0% was also found effective in improving TSS and total sugar content of fruit. Evidently, foliar feeding of ZnSO_4 (1.0%) could be recommended for improving fruit quality in litchi cv Bombai.
